If the pH of your blood falls below 7.35, the result is a condition called acidosis, a state that leads to central nervous system depression. Severe acidosis-where blood pH falls below 7.00 - can lead to a coma and even death. If the pH of your blood rises above 7.45, the result is alkalosis.
The pH level is a measure of acidity or alkalinity, on a scale of zero to fourteen, with zero being most acid, fourteen being most alkaline and seven being mid-range. The most critical pH balance is in the blood. Acidic Alkaline Normal blood pH has a very small window of acid/alkaline pH balance.
